A 20-year-old Arizona State University student in the Sigma Alpha Epsilon fraternity was dumped at a hospital by his "friends" after a tequila-drinking contest, which nearly killed the student, who had a .47 blood-alcohol level.

Tempe Police Sergeant Michael Pooley tells New Times that the student, who was interviewed the next day, told officers that he had 20 shots of tequila, then "everything after that was a blur."

The student said he and his friends, who also happened to be members of the same fraternity, started drinking around 3 or 4 p.m. on Saturday, which eventually morphed into a tequila-drinking contest, Pooley says.

Eventually, the student, identified as Aidan Mohr, passed out and started to vomit. And, according to one of his pals, his eyes started rolling back into his head.

Mohr's friends then debated with each other on what to do and ended up driving him to another friend's house, who wanted to "evaluate" him, Pooley says. That friend advised a trip to the hospital.

So, Mohr's "friends" put a note on him, wheeled him into the lobby of a Tempe hospital in a wheelchair, and took off.

Officers went to the hospital later that day on an unrelated matter, and a nurse informed officers about the frat boy with a .47 blood-alcohol level who was "turning blue" when he was being treated at the hospital, Pooley says. For comparison purposes, a .08 blood-alcohol level is the typical threshold for a DUI. Singer Amy Winehouse, who died from alcohol poisoning in 2011, had a blood-alcohol level of almost .42 when she died.

"Luckily, he didn't die," Pooley says. "By all means, he should have died," adding that the man started choking on his own vomit at one point.

Pooley says he probably won't be cited, but he has received a "hard lesson learned."

Although Mohr was a frat boy drinking with fellow frat boys, Pooley says, this was not a fraternity event.

The students are members of the same fraternity that included freshman Jack Culolias, who drowned in a river near Tempe Marketplace, after getting kicked out of a bar during a fraternity event there on November 30.
